Home Made co2 for Grow box

ok so i just made a mixture of 3/4 cup of sugar 1 teaspoon of dry yeast and 5 cups of warm water in a bottle and put a hole in the cap and put it on..

if i put this bottle in my small 1 metre sq foot grow box will this produce more co2 for the plants?

i want a cheap easy way to create co2 =]

i'd like to know about this also^
BUMP

You two should just use this website to find it. In less than a minute I found these links:

Good luck you two

Those are a couple of interesting links...I'm curious about the co2 levels created by this? The tank and timer method will cost me just over $100 and a tank is $170 with $25 refill. The tank will last about 170 days with a 7 foot by 11 foot room.

I actually tried 1/2 the recipe that "firsttimegrowing" used, and my CO2 within my 1.5 ft L x 1.5ft w x 2ft h rose to 300-350 ppm (and keeping steady) according to my CO2 monitor, so yes, it does work. I will try with more when i transfer my sprouts to my larger 5 cubic ft veg box. I will probably try 10x the amount in my veg box.

BTW, my initial CO2 ppm in my sprout box was 450pp on average, so it rose to about 800 ppm.

Look into CalCarb by Xtreme Gardening. It's a folliar spray that helps the plant attract more Co2.
